In the construction of laminated circular paper containers such asbutter tubs and the like, it becomes desirable to form fianged end wallsfor the containers. A flanged end wall of lesser 55 dimensions than theside wall of the container is inserted within the lower end of the sameand forms a bottom for the container. A flanged end wall of largerdimensions than the side wall of the container ts over the top of thesame and forms a removable closure. The present inventionprovides amachine by means of which both end walls of the containers can beautomatically constructed.

My invention comprises a reel A on which a roll of paper 20 is mountedand from which a strip 2| unrolled from the roll is carried through themachine. The strip 2| passes through a paper tensioning device B bymeans of which the paper is properly directed to a paper feed mechanismC. 'Ihe paper feed mechanism C operates intermittently to unrollsections of the strip which are cut of! into individual sheets by a cutoff device D for assembly into the composite container end. Prior toseverance of the strip the same is notched by means of a notching deviceE so that the individual sheets become octagonal in form, whereby thesame may be more conven- Y iently manipulated as the sheets areoperatedupon by the machine. The individual sheets are deposited upon a turningdevice F which rotates every alternate sheet and discharges the sameupon a conveyor G. The conveyor G delivers the sheets to a gluing deviceH which applies glue to a certain number of sheets in succession. Bymeans of a skip gluing mechanism I each seventh sheet in the particularform o`f the invention shown is deprived of glue so that the exposedsurface of the sheets of the stack forming the end wall blank arewithout glue. From the gluing device the sheets are delivered to anassembling device-J where the same are placed one upon an- Y other withthe lowermost and uppermost sheets arranged with the unglued surfaceslowermost and uppermost. A feed mechanism K takes the the ironingmechanism to a trimmer N bly means of which the composite structure iscut` circular in form to form a blank suitable for insertion into Athepress P. The conveying mechanism O moves the trimmed blank from thetrimmer to the press. After the blank has passed through the press thesame is discharged from the machine through a discharge device Q. Thesevarious parts and the framework for supporting the same together withthe driving mechanism therefor will now be described in detail.

The framework of the invention consists of two longitudinal framemembers 22 and 23 which rest upon the oor or other structure on whichthe machine is to be supported. These frame members are tied together bymeans of transverse frame members 24, 25 and 26. At the far end of themachine are provided two uprights 21 and 28 and intermediate the ends ofthe frame members 22 and 23 are provided similar uprights 3| and 32. Thetwo uprights 3| and 21 are connected together by means of a longitudinalframe member 33, while the uprights 28 and 32 are similarly connectedtogether by a longitudinal frame member 34. The two uprights 21 and 28are secured together by means of a transverse frame member 35 which isconstructed with flanges 36 bolted to the upper ends of the saiduprights. In a similar manner an angle frame member 31 vconnects the twouprights 3| and 32 together. In between the horizontal frame members 22and 33 is provided an upright 38 which is disposed intermediate the endsof the framemember l33. A corresponding upright 39 is disposed betweenth longitudinal frame members 3| and 32.

For the purpose of driving the various mechanisms and devices of theinvention, an electric motor 42 is employed which is best shown in Fig.3. This motor is mounted cna plate 43 secured to the longitudinal framemember 22. The motor 42 has an armature shaft 44 which carries a pulley45. A belt `46 passes over this pulley and another pulley 48. The pulley48 is secured to a sleeve 49 which in turn has attached to it a spurpinion 5|. The lsleeve 49 is rotatable on a stub shaft 52 which isrigidly mounted in a bracket 63 secured to upright 3| of the frameworkof the invention, as best shown in Fig. 8.

The stub shaft 52 is held attached to said bracket by means of a nut 54and the other end of said shaft enlarged to hold the sleeve 49-rotatably mounted thereon. The pinion 5| meshes with a spur gear 55constituting one of the gears of a gear cluster 56. This gear clusterincludes the gear 55 and another pinion 51. The gear cluster 56 isrotatable on another stub shaft 58 which is secured to the bracket 53 bymeans of a nut 59. The pinion 51 meshes with a gear 6| which is one ofthe gears of a gear cluster 62. The gear cluster 62 includes a.A pinion63 and is mounted for rotation on a stub shaft 64 which is directlyattached to the upright 3| by means of a nut 65. 'Ihe pinion 63 mesheswith a large spur gear 66 which is rigidly attached to* the main driveshaft 61. Main drive shaft 61 is journaled in bearings formed in theuprights 3| and A32 which have not been illustrated in `the drawings.The shaft 61 extends completely across the ma-v chine and is provided atits other end as shown in Fig. 2 with a bevel gear 68. This bevel gearmeshes with a bevel gear 69 fast on a longitudinally extending'countershaft 1| arranged in close proximity to the longitudinal framemember 34. The shaft 1| is journaled in a bearing 12 mounted on upright32 and in another bearing 13. Attached to the rearward portion of the.two uprights 21 and 28 are two rearwardly extending brackets 14 and 15.These brackets are connected together at their outermost ends by l meansof a U-shaped frame member 16. The

gear is one of the gears of a gear cluster 8| whichv is rotatablymounted 'on a stub shaft 82. This is best shown in Fig. 15. The othergear of this gear cluster is a sp'ur pinion 83 which meshes with a spurgear 84 also shown in Fig. 2. Spur gear 84 is fast on a shaft 85 whichextends across the two brackets 14 and 15 and is journaled in bearings86 and 81 secured to said brackets. All of the parts of the inventionare driven from these various shafts as will be presently more fullydescribed.

The reel A on which the roll of paper 26 is supported consists of twostandards 88 and 89 which are secured to the longitudinal frame members22 and 23. These standards, as best .shown in Fig. 1,y are provided withsockets 9| mto which may be set a shaft 82. Shaft 92 sioning device B issupported on two standards 95 l and 96 which are secured to thelongitudinal framey membersV 22- and `23- and are braced from theuprights 3| and 32v by means of braces 90. As best shown inv Fig. '4vtwo brackets 91 and 98 .are secured to said standards in a manner to bepresently described in detail. These brackets are held in proper spacedrelation by means of a tie rod 99.

Two rolls and |02`are journaled'in bearings |03 formed in the brackets.91- and 98. y These rolls are'arranged so that theroll .|02 is forwardof the roll '|0| and so that the upper portion of said roll is above thelowerportion ofthe roll .|0I. The strip 2 I passes in between theserolls and is slightly tensionedthereby so' that the paper. is kept tautwhile -traveling through theI machine. i

The paper strip 2| is fed from the tensioning device Bl tothe cut oiydevice D by means of the paper feed mechanism C. This-feed mechanismis' best shown in Figs.I 1, 2, .3 and 6. Extending across the twolongitudinal frame members 22 and 23 isa shaft |04 which isijournaled inbearings |05 and |06 securedtothe same. The shaft |04 has attached toittwo vertically lextending arms |01 and |08 which have secured to theirupper kends a cross bar- |09. Bar|09 is fast `to the arms |01 and |08and carries a gripper nger which is rigidly secured thereto. Below thebar |09 is a shaft I |2 which is journaled for rotation in bearings ||3formed in the arms |01 and |08. This shaftk carries a complementalgripper linger I |44 and upon rotation of thek particular shaft, nger||4 is brought into engagement with finger III togrip the stripf2| ofpaper passing between the same. Y

The paper feed mechanism C is operated in the followng manner: Attachedto the shaft ||2 in close proximity to arm |01 is a depending arm I5which has pivotally connected to it a link I6. rI1his `link is in turnpivotally Vconnected to a crank pin ||'1 mounted on a bracket I0attached to the gear 66 previously referred to. The arm ||5 has a lug I8secured to the same which is adapted to engage the arm |01 to limit therotation of shaft I|2 in one direction. Engagement of the fingers I4 andlimits the movement of the shaft ||2 in the opposite direction. It willthus be comprehended that as the shaft 61 rotates, crank pin ||1 iscarried-around with it and the two arms |01l and |08 oscillated back andforth. As the arms |01 and |08 travel away from the tensioning device Bthe actuating force is transmitted through arm I I5 and the finger I4forced against finger |II. This grips the paper and advances the paperthrough the machine. When the arms |01 and |08 are moved in the oppositedirection the force being again transmitted through arm ||5, said arm isirst moved so that the finger I I4 is disengaged from the finger |I I.As soon as lug I8 engages arm. |01, the arms |01 and |08 travel towardthe tensioningl device Band during such movement the fingers and ||4being spaced travel freely along the paper without feeding the sane.

For the purpose of stabilizing the action of the.

paper feeding mechanism, a cross head I I 9 is employed which isattached to shaft |04. This cross head has pivoted to it two plungersI2| and |22. These plungers are slidably mounted in a guideway |23, Fig.7, which is secured to the longitudinal frame member 22. By means ofthis construction; the plungers |2| and |22 may recipro- V cate in avertical direction as the shaft |04 oscillates. Encircling the twoplungers |2| and |22 are compressiony coil springs |24 which are seatedagainst the guide |23 and against collars |25 fast on said plungers.These springs stabilize the movement of the feed mechanism, preventing ajerky operation of the same. Y

In orderto move advantageously handle the sheets of paper which are`built into the blank for constructing the container` end walls it isdesirable that the said lsheets be octagonal in form rather than square.To so form the sheets, the same are notched before being cut intosections,

yby means of the notching device E. This device is best shown .in Figs.l, 4;and.5. Attached to the two standards 95and 96 are two brackets |36and -4 |31 andbolted thereto are two notched die blocks |26 and |21.Cooperating with said die yblocks are two angle cutters |28 and |29which are attached. to arms |3| and |32. These` arms are When the armsand |29 cooperate Withthe die blocks'l26 and |21 to cut notches in thestrip 2| passing between the said cutters and die blocks.

The notching device D isv operated in the following manner: Attached tothe main drive shaft 61 is a spur gear |38, Fig. 2. This spur gearmeshes with another spur gear |39. Gear |39 is mounted for rotation on astub shaft |4| which is secured to a bracket |42 shown in Fig. 1 whichis attached to upright 32. 'I'he gear |39 has secured to it a crank pin|43 which has pivoted to it one endof a connecting rod |44. Rod |44 hassecured to it a collar |45 best shown in. Fig. 1 which is adapted toengage one of the arms of a bell crank |46. The bell crank |46, as shownin Fig. 4, is pivoted to a bracket |41 which in turn is secured to theupright 96. 'I'he other arm of this bell crank is pivotally and slidablyconnected to the end of an arm |48 which is secured to the shaft |33 towhich arm |3| is attached. It will be comprehended that as theconnecting rod |44 is moved toward the left, as shown in Figs. 1 and 2,that the collar |45 engages bell crank |46 and swings the same in amanner to cause the cutter |28 to move downwardly and to engage the dieblock |26 and cut the sheet passing between said cutter and die block.For simultaneously operating cutter |29 a gear segment |49 is attachedto the shaft 34 to which arm |32 is attached. A lever |5| is pivoted tothe standard 95 by means of a bolt |52 and is constructed with a gearsegment |53 which meshes with the gear segment |49. As this lever isoperated the shaft |34 is turned in the opposite direction. A link |54conf nects the arm |48 with lever |5I. A tension coil spring |55 isconnected to the link |54 and to the standard 95. This spring operatesto raise the `arms |3| and |32 and to move the cutters |28 and deviceand discharges the same into a suitable receptacle placed beneath themachine.

In order to prevent the notched sheet from jumping up from the dieblocks |26 and |21 when the cutters |28 and |29 are raised, two guide1ingers |51 and |58 are employed. These fingers are attached to a rod|59 which is rigidly secured to the uprights 95 and 96. A

The notched strip 2| on leaving the notching device E is fed by means ofthe paper feeding mechanism C to the cut off device D. This dievice isAbest shown in Figs. 7 and 8, and includes a shaft |6| which isjournaled in bearings |62 and |63 formed on the upper ends of theuprights 3| and 32. This shaft has secured to it a number of arms |64which have attached to them a rotary cutter blade |65. This bladecooperates with a bed knife |66 which is attached to the transverseframe member 31. The shaft |6| rotates'in a clockwise direction asviewed in Fig. 7, and engages the bed knife |66 to cut off the sectionsof the strip to form the sheets from which the end wall blank isconstructed. The cutter D is so arranged that the line of severance ofthe sheets from the strip occurs at the vertex of the notches formed bythe notching device E so that the sheets severed become octagonal inform.

The shaft |6| is driven in the following manner: Attached to the end ofthis shaft is a spur gear |61, Fig. 2, which meshes with the spur gear|38 fast on the main drive shaft 61.

For the purpose of holding the paper from,

movement during the operation of the cut off device, a grippingmechanism is providedewhich is best shown in Figs. 3 and 7. This devicecomprises a movable gripper bar |69 which isattached to two arms |1|secured to a transverse shaft |12. This bar has a pad |68 attached to itwhich is adapted to engage the upper surface of the transverse framemember 31. Shaft |12 is journaled in bearings y|13 secured to theuprghts 3| and 32. This shaft as shown in Fig. 3 has attached to it anarm |14 which carries at its outer end aroller |15. Roller |15 engages acam |16 fast on shaft |6|. As the raised portion of the cam engagesroller |15, the gripper bar |69 is moved away from the gripper bar |68and the paper may travel freely between the two bars |68 and |69. Bymeans oa tension coil spring |11 acting between one of the arms l|1| andthe transverse frame member 31', the gripper bars :are

. brought together when the roller |15 engages the low portion o f thecam |16.

The sections of the strip upon being severed by the cut olf device D aredeposited upon conveyor G, best shown in Figs. '7 and 8. This conveyorconsists of two belts |18 and |19 which pass over pulleys |8| and |82mounted on two shafts |83 and |84. Pivoted to the main drive shaft 61are two arms |85 and |86. These arms are held in spaced relation bymeans of two rods |81 and |88 which have nuts |89 screwed upon the outerends of the same. The two shafts |83 and |84 are journaled in bearings|9| and |92 formed in said arms and are held in proper position withrespect thereto by means of the pulleys |8| and |82. The belts |18 and|19 also pass over idler pulleys |93 which are mounted in arms |94attached to the rod |88. These arms are clamped between the ends of therods |88 and arms and |86 and are'held in position by nuts |89 holdingrod |88 attached to said arms |85 and |86. By means of this constructionthe tension in the two belts |18 and |19 may be regulated. 'I'he twoarms |85 and |86 have .counterweights |95 secured to the outer endssheets to the gluing device and for the purpose y of permitting theturning device to rdtate the sheets.

The conveyor G is driven in the following manner: Attached to the maindrive shaft 61 is a sprocket |96. A chain sprocket and over twosprockets mounted on the shafts |63 and |84, not-shown in the drawings.This chain drives both the shafts |83l and- |84 and in this mannerprocures rotation of the pulleys '|8| and |82 in a direction to causethe upper runs of the belts |18 and |19 to travel toward the gluingdevice H.

'Ihe conveyor G is raised and lowered in the following manner: Attachedto the main drive shaft 61, as shown in Fig. 10, is a spur pinion |98.

lThis spur pinion meshes with a spur gear |99 which is mounted forrotation on a stud 20| secured to the upright 32. The spur gear |99 has|91 passes over this attached to it a cam 202. An arm 203 pivoted at 204to the upright 32 carries a roller 205 which engages the cam 202. Arm203 has pivoted to it a link 206 which is also shown in Fig. 8. Thislink is in turn pivoted to the arm |86 of conveyor G, whereby the saidconveyor is raised and lowered as the roller 205 follows the cam 202.

The turning device F is best shown in Figs. 1, 3, 7, 8 and 10. Attachedto the upright 32 is a bracket 201 which extends transversely of themachine and which is provided at its inner end with a bearing 208.Rotatably mounted in 'this bearing is a Vertical shaft 209 which issituated centrally of the sheet severed by the cut off device E. Thisvshaft has attached to the'upper end of the same a turntable 2|| whichis provided with a boss 2|2 secured to said shaft. The lower end of thisboss has attached to it an outwardly extending arm 2|3. .A sleeve 2|4disposed between the boss 2|2 and the bearing 208 holds the turntable2|| at the proper elevation. The' upper portion of the turntable 2|| iscupped as indicated at 2|5 for a purpose to be subsequently more fullydescribed. The turntable 2|| is oscillated through an yangle of ninetydegrees by means of the arm 2|3.v Pivotally connected to this arm is alink 2|6 which in turn is pivoted'to an arm 2|1 attached to a shaft 2|8.Shaft 2| 8 which in turn is journaled in another bearing 2|9 secured tothe longitudinal frame member 22.

The shaft 2|8 has attached to it an upstanding arm 22|. This arm hasattachedto it a cam 222. This cam is adapted to be engaged byI a roller34| which is rotatably mounted on an arm 342 secured to shaft 1|.

This cam attached to a gear 245which is mounted for rotation on a stub shaft 246 attached to the lon-Lever 239 has a. counterweight 2,41 secured to the same, whereby saidroller 243 is maintained in engagementwiththe cam. It will be noted thatgear 245 meshes with another gear 248 which is attached to the maindrive shaft 61. Gear 245 is twice the size of gear 248 so that thepresser foot 23| is operated asevery alternate sheet passes through. themachine. It will be noted that-the turntable 2li is turned each time asheet is cut off by the cut off device E. However, since the presserfoot 23| is only brought into engagement with the turntable 2| for eachalternate sheetevery alternate sheet is rotated through an angle ofninety degrecs and the other sheets are caused to pass through themachine without being turned.

When the sheets are taken from the innermost portion of the roll thesheets curve in such a manner that the same cannot be convenientlyrotated by the turning device. By constructing the turntable 21| cuppedas indicated at 2|5, the

presser foot '23| is forced into the concavity which raises the cornersof the sheets and permits the turntable to function in an efcientmanner.

To arrest the movement of the sheets when delivered to the turningdevice A a number of ngers 294 are employedwhich are secured to ahorizontally extending rod 295 disposed the proper distance from theturntable 2| This rod is fast on a swinging lever 296 which is pivotedat 291 to the horizontal frame member 34 as best seen in Figs. 2, 8, 9and 10. 4This lever carries a roller 298 which engages a cam 299, Fig.9, which is attached to the gear |99 which rotates on the stub shaft20|. Since the cam 299 is operated by gear |99 it also operates cam 202raising and lowering the conveyor G. It becomes evident that the cam 299must have two depressions 30| and 302 so that the sheets are arrestedprior to entering the gluing device, both when the sheets travelythrough in the regularl manner and when the sheets are rotated. Thefingers 294 in addition to arresting the sheets cause the sheets tostraighten out so that the same are squarely fed into the gluing device.l

The sheets delivered upon the conveyor G are centered with respect tothe turning device F by means of two adjusting plates 303 and 304 bestshown in Fig. 19. These plates are attached to vertically extending arms305 and 306 which are pivoted to bearings 301 and 308 secured to thelongitudinal frame members 23 and 22. The arm 305 has secured to itahorizontally extending arm 309 while the arm 306 has secured to it. ahorizontally extending arm 3| bifurcated as indicated at 3|4 and isconstructed with a slot 3|3 extending through the end of the same. Theextreme end .of the arm 3|| extends into the bifurcated portion 3|4 ofarm 309 and is provided with a pin 3|2 secured thereto, which fits inthe slot 3|3. By means of this construction the two adjusting plates 303and 304 may travel simultaneously vinwardly or out- The arm 309 isv anarm 3|5 is employed which is pivoted in a bearing 3|6 secured to theframe member 23. A link 3|1 pivoted to this arm and to the arm 305causes simultaneous movement of the two plates 303 and 304 upon swingingmovement of the arm 3|5 in a vertical plane. Arm 3|5 has secured to theupper portion of the same a cam 3|0 which is adapted to be engaged by acam roller 3|9 rotatably mounted upon the end of a short arm 32 I,'I'his arm is rigidly secured to the shaft 1| previously referred to.The arm 32| is so positioned that the adjusting plates 303 and 304 movesimultaneously with the fingers 294 to properly position the sheet withreference to the turntable 2| and also hold the sheet until the presserfoot 23| is lowered into engagement with the sheet. Immediatelythereafter the adjusting plates 303 and 304 are disengaged from thesheetY and likewise the fingers 294., For the purpose of disengaging theadjusting plates 303 and 304 from the positioned sheets, a tensioncoilspring 322 is employed which is secured at one end to the arm 306 and atits other end to a support 323 secured to frame member 22. This springnormally holds the two plates away from the sheets and urges the cam 3|8against the roller 3|9.

The gluing device H is best shown in Figs. l, '7 and 8. This deviceincludes two bearing blocks 25| and 252 which are attached to thelongitudinal frame members 33 and 34. Between these bearing blocks ismounted a glue pan 253 which is supported by said blocks in any suitablemanner. Journaled in suitable bearings formed in the bearing blocks 25|and 252 are two main glue rollers 254 and 255. A distributor roll 256 is'also journaled in the said bearing blocks 25| and 252 and is adapted topress'against the roll 255. roll is adjustably urged against the roll255 by means of adjusting screws 251 which operate in the customarymanner to move the roll 256 toward the roll 255. 'I'he roll 255 isadapted to dip into the glue within the glue pan 253 and carries a filmof glue over to the roll 254 which transfers it to the sheet passingbeneath the same. The bearing blocks 25| and 252 also support a guideroll 258 which assists in moving the sheet to be coated to the main gluerolls 254 and 255.

For bringing the sheet to be coated in contact with the glue roll 254two presser rolls 26| and 262 are employed. These rolls are journaled intwo arms 260 and 263, Fig. 12, which are attached to a shaft 264. Shaft264 is mounted for oscillation in bearings 259 formed in thelongitudinal frame members 33 and 34. When the two 'rolls 26| and 262are lowermost as shown in Fig.

A the roll 254 and the same are not coated with glue. When the rolls areraised as shown in Fig. 7, the sheet is brought in contact with the roll254 and gluing of the sheet occurs. The feeding of the sheets to theglue roll 254 is procured by the conveyor G. This conveyor when elevatedas s hown in Fig. 7 brings the upper run of the belts |18 and |19 intocontact with the roll 258 which procures a positive feed of the paperbeneath the glue pan 253 and the roll 254. A flexible finger 265 engagesthe presser roll 262 and keeps the skeet more firmly in contacttherewith. 'This assists in feeding the sheet and also prevents thesheet from rolling around the roll 254. When the rolls 26| and 262 aredepressed as shown in Fig. 8 this finger 265 holds the sheet away fromthe roll 254.

To positively guide the sheets up to the roll 262 a number of arms 266are employed which same is brought into engagement with' the roll Thevarious glue` rolls are driven in a manner best shown in Figs. 2 and 18.Meshed with the gear |61 which is mounted on the sha-ft |6| is a spurygear 261 which is journaled on a stub shaft 268 secured to thelongitudinal frame member 34. This gear meshes with another idler gear269 which is similarly mounted on a stub/ shaft 21| also secured to thelongitudinal frame member 34. The gear 269 meshes with a gear 212 whichforms the larger gear of a gear cluster 213. This gear cluster ismounted for rotation on a stub shaft 214 secured to the longitudinalframe member 34. The smaller gear of this gear cluster which is notshown meshes with a gear 21|), being one of the gears of another gearcluster 215. This gear cluster is mounted on a stub shaft 216 which isalso secured to the longitudinal frame member 34. Gear 215 meshes withagear 211 secured to the trunnion of roll 254. This roll trunnion hasattached to it still another gear 218 which meshes with a. gear 219 faston the trunnion of roll 255. lIn this manner both rolls 254 and 255 arepositively driven. The gear 218 also meshes with a pinion 28| fast onthe trunnion of roll 256 so that the said roll is correspondinglyrotated. The two rolls 26| and 262 as shown in Fig. 18 are provided withsprockets 282 and 283. These sprockets engage a chain 284 which passesover a sprocket 285 on one of the trunnions of roll 254 and which alsopasses over an idler sprocket 286 supported on a lever ,l

281. This lever is pivoted to a bracket 288 attached to the longitudinalframe member 33 and carries a weight 289 by means yof which the chain284 is kept suitably tensioned. In this manner both the rolls 26| and262 are positively driven. The roll 258 also has attached to one of itstrunnions a sprocket, not shown. A chain 292, Fig. 3, passes over thissprocket and another sprocket secured to a trunnion of the roll 254.

In order that the top sheet be free from glue so that both the ,top andbottom section are without glue upon their exposed surfaces, skip gluingmechanism I is utilized. This skip gluing mechanism embodies the tworolls 26| and 262 and the supports therefor and has for its purpose tomove said rolls downwardly and away from the roll 254. The two arms 260and 2,63

' are mounted on theshaft 264 as previously e'xplained and when the saidarms are rocked the rolls 26| and 262 are lowered. For this purpose adepending arm 324, shown in Figs. 7 and 8, isA

employed which is attached to the arm 266. 'I'his arm has pivoted to ita link 325 which in turn is pivoted to the upper end of another arm 326.Arm 326 is'fast on the sleeve 220 which is journaled for oscillation inthe bearings 2|9 mounted on frame member 22. As this shaft oscillatesthe rolls 26| and 262 are alternately raised and lowered to bring thesheet in contact with the roll 254 or to drop the sheet below the same.

The sleeve 220 is` oscillated in the following manner: Attached to thesleeve is an upstanding arm 343 (Fig. 12) which has pivoted to the upperend thereof a longitudinally extending link 344 shown in Figs. 3 and 17.This link extends rearwarly of the machine and is pivoted to a lever346. Lever 346 is pivoted on a stud 228 which is secured to the bracket14. 'I'his lever has rotatably mounted at its other lend a roller 341`longitudinal frame members 33 and 34.

y movement of the lever. 324. This moves the rolls 26| and 262 from thepositions shown in Fig. 8 to the position shown in Fig. 'I and viceversa.

In order to prevent the glued sheet from following around the roll 254an idler roll 321 is employed which is rotatably mounted in bearingssecured to a cross bar 328. This cross bar is supported on two hookedbrackets 329 which are secured to the bearing blocks 25| and 252. Thesebrackets also provide bearings yfor a transverse shaft 33| whichsupports two depending hooked arms 332. Arms 332 rotatably support twosmall rolls 333 which straddle the roll 321. The rolls 333 are disposedbelow the lowermost portion of the roll 254 and can be moved from theposition shown in Fig. 8 to that shown in Fig. '1. When in the latterposition rolls 333 are out of the way and the sheets engaging the glueroll 254 travel freely beneath the same and are discharged to theassembling device J. When the rolls 333 are in the position shown inFig. 8 the said rolls engage the roll 26| and assist in maintaining thesheets out of contact with the roll 254 son that thev sheets may passthrough the device without' vvice are delivered to the assembling deviceJ, the

description of which will now follow. 'I'his assembling device is bestshown in Figs. 11 and 12 and includes two temporary supports 35| and 352which consist of plates disposed in proximity to the frame members 33and 34 and somewhat above the same. These plates are supported byhangers 353 and 354 which are pivotally connected to two posts 355 and356 secured to the The hangers 353 and 354 may swing toward and from thecenter of the device to bring the temporary supports 35| and 352 inpositions where the same may support the sheets fed from the gluingdevice H. When the sheet-is in position upon these supports the saidsupports are moved away from the center of the machine and the gluedsheet is dropped, the same falling upon a table 351 secured to thelongitudinal frame members 33 and 34.

The two temporary supports 35| and 352 are moved in the followingmanner: Pivoted to the post 355 at 358 is a vertically extending lever359. The upper end of this lever has pivoted to bracket 365 secured vtopost 356 and the other end of said bell. crank has pivoted to it a link366 (Fig. 1) which in'turn is pivoted to a pin 361 on an arm 368. Arm368 is rotatably mounted on. a stub shaft 369 which is securedto abracket 31| mounted on horizontal frame member 34. The arm 3 68 hasrotatably mounted on it a roller 312 which engages a cam 313 fast onshaft |6| previously referred to. As this shaft rotates, cam

313 `oscillates the arm 368 which causes simultaneous movementoi the twohangers 353 and 354 and they temporary supports 35| and V352 carriedby`the same toward and from each other.

.Acounter weight 318 attached to the arm 368 maintains the roller 312 inengagement with the cam 313.

.In order tov prevent the sheets deposited upon thetemporary supports35| land 352 from following either of thesupports, a number ofvertically extendingztngersl 314 and315 are employed which aredisposedoutwardly of the lateral edges of the sheets,l and whicharemovable laterally in slots 380 in the temporarysupports 35| and 352and inV the `table 351. Fingers 314 are mounted -on across head. 316which is attached to avertically extending arm 311.. lFingers 314 are'similarly mounted on a crosshead 318 which is attached .to a vertically.extending arm 319.' Arm 311 is pivotally mounted in a bearing 38|secured to horizontal frame member 22 and arm 319 is similarly mountedin a bearing 382 secured to thev horizontal frame member 23. The twoarms 311 and 319 are connected together by means of two links l383 `and384 which are pivoted at their inner ends to a yoke385 and at theirouter ends to the arms 311and 319. A rod 386r is slidably mounted in theyoke 385 andis guided for movement in a cross bar 48| secured to twodepending brackets 482 and 483` attached to the longitudinal framemembers 33 and 34. This rod has secured to it a clevis 381 which ispivoted to one arm 388 of a bell crank 389. Bell crank 389 is pivotedona stub shaft 39| secured to a bearing 392 fast on horizontal framemember 23. The other arm 393 of this. bell crank extends upwardly andhas attached to it a cam 394. A roller 395 rotatably mounted on an arm396 is adapted to engage this cam and to move the arm 393 inwardly. Arm,396 is attached to the shaft 1|. The rod 386 has secured to it twocollars 391 and 398 which are collar 398 and to the link 383 and servesto move the cam 394 toward the shaft 1| and to lower the links 383 and384 so as to move the ingers 314 and 315 toward one another. Fingers 314and 315 by means of the movement imparted to the same through cam 394center the sheets and arrange the same in proper position over the table351.

For vlimiting the movement of the sheets delivered tothe assemblingdevice J an end stop 484 is employed which is secured to the upper endof a vertical arm 485 as shown in Fig. 11. 'I'his stop is disposed inproximity to the ironing mechanism L which consists of two rolls 486 and481 and bears against the lowermost roll 486 thereof. The lowermost endof the arm 485 is pivoted to another arm 488 which in turn is secured toa shaft 489. Shaft 489 is mounted for rotation in a bearing 4|| (Fig. 2)secured to the upright 39. This shaft has attached to its outer end adepending arm 4|2 which is drilled to receive the end of a connectingrod 4|3. Connecting rod 4| 3 has two collars 4|4 and 415 attached to thesame which engage the arm 4|'2 on opposite sides and which serve tooscillate the shaft 489 as the connecting rod 4|3 is reciprocated. Theconnecting rod 4|3 is provided at its other end with a clevis 4|6 whichis pivoted to an arm 4|1 mounted for oscillation'o'n a stub shaft 4|8secured vto the bracket 15. Arm 4|1 has securedto it a bent arm 4|8which .has rotatably mounted at the end thereof a roller 4|9. Roller 4|9engages a camr 42| which is mounted on shaft 85. A counter weight 422secured to the arm 4| 1 maintains the roll'er 4|9 -in engagement withthe cam 42|. As the shaft 85 rotates, end stop 484 is, moved fromthevposition shown in Fig. 11 which arrests the movement of the sheettoward the ironing mechanism L to a positionr below the level of thetable 351 permitting` the 'sheet to be fedto theironing mechanism.

`In order' to cause the sheets` to descend from the temporary supports35| and 352 tothe table 351 and to furtherprevent the sheets fromfollowing either of said supportsduring their movement outwardly, apresser foot 423 is employed which is shown in Fig..12 and isconstructed in the form of a vroller journaled in a clevis 424 securedto a depending rod 425. This rod is pivoted to a lever 426 which in turnis pivoted at 421 to a bracket y428 securedto the horizontal framemember ,34. The lever 426 is provided at its end with a roller 429whichis adapted to engage a cam 43| fast on the shaft 1|. This cam is sotimed. that as the temporary supports 35| and 352 are moved outwardlythe presser `foot 423 descends and forces the sheet down upon the table351.

'Ihe sheets leaving the' gluing device H are delivered to the assemblingdevice J in the. following manner: The two rolls 26| and 262 arepositively driven by the chain 284 and the sheets resting upon the sameare positively progressed toward the assembling device. Movement of thesheets is procured through these rolls whether the sheets are inengagement with the roll `254 or free therefrom and the movement of thesheet by these rolls is rapid enough so that the sheets are slid alongthe temporary suports 35| and 352 and until they engage the end stop484.

The assembled 'stack of sheets after the required number of sheets havebeen assembled is moved from the assembling device J by means of thefeed mechanism K to the ironing mechanism L. 'I'he feed mechanism K willnow be described in detail which is best shown in Figs. 11 and 12.Operating in a slot 432 in table 351 is an auxiliary table 433 which isguided in said slot by means of guides 434. This table has secured tothe underside thereof bearings 435 which journal a. shaft 436. vShaft436 has rigedly secured to it a. bell crank 431 which has pivoted to thelower end of thesame a link 438. Link 438 is pivoted to the upper end ofa vertically extending arm 439 which is mounted on a shaft 44 Shaft 44|is journaled in bearings 442 secured to the horizontal frame members 22and 23. The shaft 436 has also secured to it two arms 443 which aremovable toward and from the auxiliary table 435. The movement of thesearms is limited by means of double headed rivets 444 secured t said armsand operating through suitable holes in the table, not shown. As will benoted in the drawings, table 351 is slightly below the line of tangencyof the two ironing rolls 486 and 481. The two rivets 444 `when the arm439 is moved toward the left, as shown in Fig. 11, raise the assembledsheets so that the same are substantially in the horizontal plane oftangency of said rolls, whereby the assembled sheets are readily fedinto the rolls.

The shaft 44| is operated in the following manner: Secured to the shaft44| is an upwardly extending arm 445 which has pivoted to the upper endof the same a link 446. Link 446 is pivoted to a bell crank 441 which ismounted for oscillation upon the stub shaft 220. This bell crank isprovided with a roller 440 (Fig. 17) which is adapted to engage a cam449 secured to the gear 224. This cam is driven by shaft 05 through thegear 223 and serves to reciprocate the link 446 and to move theauxiliary table 433. A counter weight 440 secured to an arm 450 which isattached to shaft 44| operates to maintain the roller 440, in engagementwith cam 449 and to move the auxiliary table 433 rearwardly to theIposition shown in Fig. 11. The table 433 is provided with a lip 45|which extends upwardlyv therefrom at the rearward edge of the same whichengages the stack of sheets and progresses the same toward the ironingdevice L.

The ironing mechanism L as previously described, comprises two rolls 406and 401 whichv and have bearing blocks therein in which the trunnions ofthe roll 401 are journaled and which are l urged downwardly by means ofsuitable springs to provide yielding pressure between the rolls 401 and406. 'I'he pressure between these rolls can be adjusted by means ofadjusting screws 453 provided for the bearings 452. In this manner anydesired pressure can be lexerted upon the assembled sheets and as thestack ,of sheets pass between the rolls the sameare ironed and pressedtogether and a composite structure is provided suitable for pressinginto the flanged end wall structure.

The rolls 401 and 406 are driven in a manner best shown in Fig. 2.,Attached to the shaft 216 is a sprocket wheel 454. A chain 455 passesover this sprocket wheel and another sprocket wheel 456 fast on thetrunnion 459 of roll 401. The rolls 401 and`406 have intermeshing gears46| and 462 by means of which the lowermost roll 406 is driven from theroll 401.

The ironed stack of i sheets or the blank from which the end walls areconstructed is fed from the ironing mechanism L to'the trimmer N bymeans of conveyor M, best shown in Fig. 1.3.

'I'his conveyor consists of two rolls 463 and 46i4.

The roll 463 is secured to a shaft 465 which is mounted for rotation inbearings466 and 461 of which the bearing 461 is secured to thelongitudinally extending frame member 33. A plate 468 connects the twobearings 461 and v466 to- Bearings 41| and 412 are secured to a plate413 which is attached to a bracket 414 mounted on the longitudinal framemember 30. By rotating the sleeve 469, the roll 464 can be moved towardand from the roll 463 to vary the pressure between the said rolls and toprocure a feed for the blanks leaving the ironing device L or to permitsaid blanks to travel partly through the conveyor M withoutinterference.

The rolls 463 and 464 are driven in the following manner: Attached tothe end of the shaft 465 is a sprocket wheel 415. A chain 416 passesabout this sprocket wheel and another sprocket wheel 411 secured to thetrunnion 450 of the ironing roll 401. In this manner shaft 465 ispositively driven. Attached to this shaft is a spur gear 410 whichmeshes with a corresponding spur gear 419 on shaft 410.

The sleeve 469 is rotated for the purpose of moving the roll 464 towardthe roll 463 by a mechanism best shown in Fig. 11. Journaled in abearing 40| secured to the longitudinal frame member 33 is a 'shortshaft 402. This shaft carries a depending arm 403 which has pivoted toit a link 404. Link 404 is in turn pivoted to a bell crank 405 which inturn is pivoted at 406 to the upright 30. 'Ihis bell crank has pivotedto it a lirik 401 which isV in turn pivoted to an arm 400 secured tosleeve 469. When the arm' 403 is moved toward the right, as viewed inFig, 11, arm 400 is raised and the roll 464 is moved toward the roll Theshaft 402 is oscillated in the following manner: Attached to this shaftupon the exterior of frame member 33 is a vertically extending arm 409.I'his arm has pivoted to it a link 49|. Link 49| is in turn pivoted to abell crank 492 which has rotatably mounted on itel roller 493. This bellcrank is mounted for oscillation on the stub shaft 220. The roller 493engages a cam y494 which is secured to cam 340 and travels with gear224. A counterweight 495 secured to the bell crank 492 urges the roller493 into engagement with cam 494.

To continue the feeding of the ironed stack of sheets to the trimmer Nafter conveyor M ceases to progress the same, a mechanism is employedwhich is best shown in Figs. 11, 13 and 14. Extending across the twolongitudinal frame members 2,2 and 23 is a shaft 496. This shaft isjournaled in bearings 491 and 490 attached to the frame members 22 and23 and is held from axial movement therein by means of collars 499pivoted to them dogs 5|3 (Fig. 11) which operate` at the point oftangency of the rolls and which take the ironed stack of sheets afterthe same leave the rolls and progress the said sheets'up to the trimmerM.

The shaft 496 is operated in the following manner: Attached to the outerend of said shaft is a vertically extending arm 5|4`which is constructedwith-a hub 5|5 rigidly secured to said shaft. I'he upper endof this armhas pivoted to it a link 5|6 which extends rearwardly'of the machine andwhich is best shown invFig. 3l This link is pivoted't'o a bell crank 5|1(Fig. 1'1 which carries a roller 5|0. This bell crank is mounted on thestub shaft 2 20. Roller 5|0 engages a cam |9 which travels with the gear224. Roller 5|8 is maintained in contact With'cam 5|9 by means of acounterweight 52| which is attached to an arm 522 secured to shaft 496.As the gear rotates the bell crank is oscillated and the shaft 496correspondingly oscillated to operate the dogs 5|3 in a manner to feedthe paper.

The trimmer N comprises a rotary table 523 and a rotary shoe 524positioned above the same. 'Ihe trimmer also includes mechanism forurging the shoe 524 against the fable 523 to cause the .same to rotate.As thestack of sheets rotates the marginal portions of the same aretrimmed by a cutter 525 best shown in detail in Fig. 14.

The table 523 is mounted on a flange 526 which is attached to a verticalshaft521. This shaft is mounted for rotation in a vertical bearing 528attached to a cross frame member 529 secured to the longitudinal framemembers 33 and 34. The shaft 521 is provided at its end with a collar53| which engages a shoulder 532 formed in the bearing 528. Acompression coil spring 533 is seated at one end against the shaft 521and at its other end in a cap 534 secured to the end of thebearing 528.This spring maintains the table 523 at the elevation of the horizontalplane of tangency of the conveyor rolls 463 and 464.

The shoe 524 is similar to the tablel523 and is mounted on a flange 535which is attached to a vertically extending shaft 536. This shaft isslidably and rotatably mounted in a bearing 531 secured to a cross framemember 538 which is4 attached to the two longitudinal frame members 33and 34. Rotatably mounted upon the upper end of the shaft 536 is a spurgear 539 which meshes with a spur pinion 54| fast on a shaft 542. Thelower end of this shaft as shown in Fig. 13 is journaled in a bearing543 which is attached to the longitudinal frame member 34. Shaft 542carries a bevel gear 544 which'meshes with another bevel gear 545 faston a shaft 546 (Fig. 2). This shaft is journaled in a bearing 541mounted Y on the longitudinal frame member 34 and carries a sprocketwheel 548. A chain 549 passes over this sprocket wheel and anothersprocket wheel 55| fast on trunnion 459 of the ironing roll 401. Thisroll is driven as previously described and affords a drive for the gear539.` Gear 539 has attached to it a jaw clutch member 552 which can beshifted vertically by means of a forked arm 553, best shown in Fig. 14.This jaw clutch member is adapted to engage another jaw clutch member554 pinned to the shaft 536. When the jaw'clutchmember 554 is broughtinto engagement with the clutch member 552, a drive is effected betweengear 539 and the shaft 536 ro' tating shoe 524.

Lever 553 is 'pivoted at 555 to a standard 556 secured to the crossframe member 538. This lever has pivoted to its outerend a dependinglink 551.which in turn is pivoted to a bell crank 558v mounted foroscillation on a shaft 559 secured to a. mounting 56| which in turn isattached to the longitudinal frame member 33. 'I'he bell crank 558 haspivoted to it alink 562 which in turn is pivoted at 563 (Fig. 17) to anoscillating member 564. This member is in turn pivoted at 565v to a.bracket 566 secured to the upright 21. The'member 564 carries tworollers 561 and 568 which engage two cams 569 and 51| fast on the shaft8 5. The two rollers 561 and 568 cause positive movement of .the link562 pivoted thereto, whereby the lever 553 is positively (raised andlowered and the shoe 524 caused to turn the stack of sheets delivered bythe same through engagement with the table 523.

The cutter 525 as shown in Fig. 14 comprises two cutter disks 512 and513 which are mounted on shafts 514 and 515. These shafts are journaledin bearings 516 and 511 attached to the longitudinal frame member 34.Upon the two shafts 514 and 515 are meshing spur gears 518 and 519,whereby the two cutter disks 512 and v513 are positively driven. Asprocket wheel 58| attached to shaft 514 is driven by means of a chain582 which passes over a sprocket wheel 583 fast on shaft 459. This shaftis driven as. previously described so that the cutter 525 operatescontinuously. The cutter 525 is situated a distance from the center ofthe shafts 536 and 531 equal to the radius of the blank to be cut fromthe assembled stack.

The assembled stack of sheets is fed into the trimmer N in such a mannerthat the said sheets just clear the cutter 525. Longitudinal movement ofthe assembled stack is terminated by means of a stop rod 584 which isslidably mounted in a guide 585 secured to an annulus 586, forming partof the press P which will be presently more fully described. This stoprod is pivoted to an arm 581 which is mounted for free swinging movementon shaft 496. As the arm 581 is oscillated stop rod 584 is caused toproject above the level of the .table 523 and to arrest movement of theassembled stack of sheets. The arm 581 is held in position on shaft 496,as shown in Fig. v14, between the hub 503 and a collar 588 secured tosaid shaft. Arm 581 has issuing forwardly from it an extension 589 bymeans of which said arm is oscillated in a manner to be presentlydescribed.

Operating in conjunction with stop rod 584 are shifter fingers 59| and592 shown in Fig. 14. The lingers 59| are attached to a verticallyextending arm 593 and the fingers 592 are similarly attached to avertically extending arm 594. Both of these arms are provided with hubs595 (Fig. 11) which are journaled on stub shafts 596 secured to brackets591 attached to the longitudinal frame members 22 and 23. The .hubs 595have rigidly attached to them arms 598 and 599 which meet at the centerof the machine and which are slidably and pivotally connected togetherby means of a joint 60| similar to the joint formed between the two arms309 and 3| illustrated in Fig. 19. The arm 594 is oscillated back andforth by means of a link 602 which is pivoted at 603 to a bracket 604secured to saidarm. Link 60| is in turn pivoted to a crank arm 605 whichis attached to a shaft 606. 'I'his shaft is journaled in a bearing 601attached to longitudinal frame member 34 and carries another arm 608extending outwardly therefrom. Arm 608 has pivoted to it at 609 a link6| which in turn is pivoted at 6| 2 to a swinging arm 6|3 mounted foroscilla.- tion on shaft 4 |8 previously referred to. Arm 6 I3 carries aroller 6|4 which engages a cam 6| 5 fast on shaft 85. A spring 6|6 actsbetween the arm I608 and the longitudinal frame member 34 and maintainsthe roller 6|4 in Contact with cam 6|5. As shaftl 85 oscillates thefingers 59| and 592 are brought together and engage the sheet .in amanner to square the sheet up and center the same with respect to thetable 523. Finger 592 is so arranged that the right hand edge of thesheet as viewed in Fig. 14 is brought right snug up to the cutter disk512 so that as soon as the drive is effected the cutter 525 shears theassembled stack of sheets in a complete circle.
